Total Lubmarine on Tuesday (4 February) launched its WT SUPRA Coolant – a coolant that claims to be an environmentally friendly inhibitor concentrate that delivers extended service life and corrosion protection using its patented carboxylate technology.

“We offer a solution to help increase operating performance and protection for both engine manufacturers and operators alike, and which gives complete assurance on their engine performance,” says Stuart Fuller, Global Brand Manager at Total Lubmarine.

Formulated using organic technologies, the product has been specifically designed for use in marine 2 stroke, 4 stroke and stationary engines as well as smaller, high speed auxiliary engines.

“WT SUPRA, contains none of the inorganic ingredients, such as phosphates, nitrates, amines, boron or silicates, typically found in other coolants,” says Fuller. “We have been careful to develop an advanced solution that reduces the need for frequent waste disposal and provides added protection to the environment with non-polluting properties. It uses the latest organic technology, delivering high performance and extended service life to equipment, reducing overall maintenance costs.”

The science behind WT SUPRA provides:

enhanced protection of wet cylinder liners at increased temperatures
exceptionally low inhibitor depletion rate ensuring long term system protection
excellent protection of engine materials against corrosion and cavitation, including aluminum, brass, copper, solder, steel, and cast iron
outstanding service life – at least 32,000 hours in engines with just a 5 vol.% concentration.

“With WT SUPRA there’s no need to introduce supplementary additives when using WT SUPRA because there is minimal depletion of the coolant’s active ingredients,” says Fuller. “It is in essence a ‘fill-for-life’ product, which saves on regular maintenance and costly downtime especially when correct top-up procedures are followed.”

“As part of this analysis we carry out aging tests that are conducted under more severe conditions compared to those commonly used in the industry. Results have shown that the organic inhibitors used in WT SUPRA provide optimal results even at high running temperatures due to its strong anti-corrosion and anti-cavitation protectors.”

Zhoushan completes China’s first batch of marine biofuel blending under pilot programme

Petrochina International Co Ltd recently said it has blended more than 30,000 metric tonnes (mt) mt of biofuel since completing the country’s first biofuel marine fuel blending operation on 13 March.

The company said the milestone demonstrates its ability to conduct continuous and large-scale biofuel marine fuel blending operations.

The company has been developing marine biofuel blending operations at China (Zhejiang) Pilot Free Trade Zone, leveraging storage and logistics facilities at its Aoshan base.

Its latest product, B24 marine fuel containing 24% biofuel component, meets relevant International Maritime Organization (IMO) requirements and marine fuel standards, according to the company. It said the product can be supplied for bunkering vessels operating on international routes.

It has used its global trading network to secure feedstock supplies and support cost control and supply security for the blending operations, it added.

The company said the large-scale blending of its marine biofuel products marks a development in China’s marine biofuel blending market.

It plans to work with upstream and downstream businesses within its group to support the development of Zhoushan Port as a major bonded marine fuel bunkering hub and contribute to its parent group’s transition towards lower-carbon energy.

Manifold Times previously reported China (Zhejiang) Pilot Free Trade Zone launching the first pilot programme for marine biofuel blending in China with the completion of the first batch of B24-HSFO.

The launch was marked with the blending of 2,000 mt of biodiesel and 6,300 mt of high sulphur fuel oil (HSFO) in storage tank F-02 of Sinochem-Xingzhong Oil Staging (Zhoushan), producing 8,300 mt of B24-HSFO.

Manifold Times also reported the first cross-regional bonded bunkering operation of blended biofuel in East China was successfully completed at the Meishan Port Area of Ningbo-Zhoushan Port.

The B24-HSFO used in the bunkering operation was supplied by the Aoshan Petroleum Base in Zhoushan from the first pilot programme for marine biofuel blending in China.

NYK wraps up first STS ammonia bunkering operation in Japan

NYK Line, on Thursday (17 September) with Japan Marine United Corporation, Nihon Shipyard Co Ltd, Mitsubishi Gas Chemical Company, and Kokuka Sangyo Co Ltd, has completed the world’s first ship-to-ship (STS) ammonia bunkering operation to an ammonia-fuelled vessel.

At a quay within Japan Marine United Corporation’s Ariake Shipyard, ammonia fuel was transferred from the ammonia carrier Shoei Maru via the STS method to an ammonia-fuelled medium gas carrier (AFMGC) scheduled for delivery in November 2026.

The operation was conducted in preparation for sea trials of the AFMGC using fuel ammonia.

“This achievement represents an important initiative that has put into practice an operation essential for the future practical deployment of ammonia-fuelled vessels,” the company said.

The bunkering operation was conducted following extensive discussions among the companies involved. Safe operating procedures and work processes were established prior to the operation, enabling the transfer to be completed safely. Through this initiative, we have accumulated practical insights regarding safe fuel supply operations.

This operation serves as a pioneering example of the fuel-supply framework that will be required for the widespread adoption of ammonia-fuelled vessels.

The AFMGC is currently in the final stage of construction and is scheduled for delivery in November 2026.

“The successful completion of this operation marks a significant milestone toward the broader commercial use of fuel ammonia and the practical deployment of ammonia-fuelled vessels. It also represents an important step forward in establishing an ammonia supply chain,” the company added.
